Research documents children's exposure to pesticides, suggests need for family education
Two studies of immigrant farmworker families in North Carolina and Virginia found evidence of pesticide exposure in young children, and prompted researchers to call for pesticide safety training for workers' spouses. view more (2006-07-18)
A new portable biosensor detects traces of contaminants in food more quickly and cheaply
Scientists at the Universitat Autonoma de Barcelona (UAB), in cooperation with the CSIC, have developed a new electro-chemical biosensor which detects the presence, in food, of very small amounts of atrazine -one of the most widely used herbicides in agriculture and which also has very long lasting effects on the environment- as well as... view more...

Pitt Research Finds That Low Concentrations of Pesticides Can Become Toxic Mixture
Ten of the world's most popular pesticides can decimate amphibian populations when mixed together even if the concentration of the individual chemicals are within limits considered safe. view more (2008-11-12)
Mayo Clinic study could lead to safer pesticides
Each year millions of dollars in crops are lost to two insects notorious for devastating farms: the greenbug (Schizaphis graminum) and the English grain aphid (Sitobion avenae). view more (2006-10-13)
Environmental chemicals implicated in cancer, say experts
New research at the University of Liverpool suggests that environmental contaminants, such as pesticides, are more influential in causing cancer than previously thought. view more (2006-03-20)
More recycling on the farm could reduce environmental problems
Growing environmental problems resulting from farming argue for a shift toward practices that use lower inputs of pesticides and energy and more recycling of energy and materials. view more (2007-05-01)
Troublesome North-American mosquitoes display resistance to insecticides
New evidence published online in Pest Management Science reports the first signs of resistance to pyrethroid insecticides in a population of mosquitoes from Marin County, California. The species in question is not only a major pest, but also acts as a vector of West Nile virus, a virus that spread rapidly westward across the United States after it... view more... (2004-01-09)
"Green" method decontaminates deadly nerve agents
Research by two scientists has resulted in an exciting new method for rapidly and safely destroying toxic agents such as chemical weapons and pesticides. view more (2008-04-09)
Mayo researcher discovers target site for developing mosquito pesticides
A Mayo Clinic researcher has discovered a target site within malaria-carrying mosquitoes that could be used to develop pesticides that are toxic to the Anopheles gambiae mosquito and other mosquito species. view more (2006-12-21)
Making an impact with pesticide assessments
With over two million tons of pesticides used annually worldwide, from 900 active ingredients, the human health and environmental risks are high. Making data from so many products used in so many environments more widely available online is helping risk assessors work out what action to take. view more (2005-03-15)
University of York spin-off company invents toxic testing device
A simple, quick and accurate hand-held kit which can be taken out into the field to test for toxic chemicals is being exploited by a spin-out company from the University of York. The BATT (Bioassay Toxicity Testing) device is now being tested by environment agencies, textile industries, water boards, and diagnostic companies involved with... view more... (2003-07-21)
Pesticides choke pathway for nature to produce nitrogen for crops
Many farmers applying pesticides to boost crop yields may instead be contributing to growth problems, scientists report in a new study. view more (2007-06-06)
New computing tool could lead to better crops and pesticides say researchers
A new computing tool that could help scientists predict how plants will react to different environmental conditions in order to create better crops, such as tastier and longer lasting tomatoes, is being developed by researchers. view more (2009-09-23)
Alternative methods proposed to detect pesticides and antibiotics in water and natural food
Water or food of natural origins (from plants or animals) that we consume on a daily basis can contain unwanted 'supplies' for our organism, such as pesticides or antibiotics. view more (2007-09-19)
Study of Latina women and children finds large variation in susceptibility to pesticides
Some newborns may be 26 to 50 times more susceptible to exposure to certain organophosphate pesticides than other newborns, and 65 to 130 times more sensitive than some adults. view more (2006-03-03)
Gene exchange common among sex-manipulating bacteria
Certain bacteria have learned to manipulate the proportion of females and males in insect populations. Now Uppsala University researchers have mapped the entire genome of a bacterium that infects a close relative of the fruit fly. view more (2009-03-26)
Bran filters chlorinated hydrocarbons and arsenic out of waste water
Compounds of arsenic and hexachlorocyclahexane (HCHs) previously occurred above all in the production of pesticides. Pesticides containing HCHs have been prohibited in Germany since the 1980s. Arsenic is still used in the semiconductor and glass industries and pollutes water and the soil in many places. Since HCHs and arsenic are carcinogenic... view more... (2002-10-11)
Mustard - hot stuff for natural pest control
Researchers, growers and Industry specialists from 22 countries will share the latest research into the use of Brassica species, such as mustard, radish, or rapeseed, to manage soil-borne pests and weeds - a technique known as biofumigation. view more (2008-07-28)
Red alert! How disease disables tomato plant's 'intruder alarm'
How a bacterium overcomes a tomato plant's defences and causes disease, by sneakily disabling the plant's intruder detection systems, is revealed in new research out today (4 December) in Current Biology. view more (2008-12-05)
Virus-resistant grapevines
A good wine needs to ripen. But it's a long way to the barrel. Even before the harvest, the grapevines have to overcome all kinds of obstacles. Extremely hot or rainy periods can destroy entire crops, not to mention the wide variety of pests that can appear on the scene. view more (2009-07-06)
